The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Winduino: The beginnings of an Arduino emulator layer for PC
This should work with LVGL but I haven't tried it. It does work with https://honeythecodewitch.com/uix and https://honeythecodewitch.com/gfx and the example project uses that.

I've produced a couple of projects for doing graphics and user-interface stuff

UI/UX and 2d graphics libraries (cross platform)
I've developed a graphics library that supports TrueType, SVG, PNG, JPG, alpha blending and X11 colors here: https://honeythecodewitch.com/gfx/

If my ESP32 is being powered by a 5V power supply through the 5V Vin pin, can I simultaneously output 3.3V to some other peripherals in the system that require 3.3Volts
The ESP32 will reboot with a brownout message if you draw too much current. Obviously you want to avoid this, but after writing a graphics library htcw_gfx and writing a ton of drivers for many different displays, I've never had any issues running the backlight off the ESP32's 3.3v pin when plugged into USB, or even on LiPO.
- Guidance on how to get started
- htcw_gfx 1.4.6 is released
- Initial SVG support in htcw_gfx 1.4.4

Just got SVG graphics rendering on an ESP32
Thx, interesting. Made me G**gle it: https://github.com/codewitch-honey-crisis/gfx

Alternatives to LVGL for embedded graphics on a monochrome display?
Try out https://github.com/codewitch-honey-crisis/gfx - it works very well on monochrome displays and is lighter than LVGL.
- htcw_gfx 1.3.8 is out and published to PIO

Creating an 8-channel, 16-bit audio recorder with ESP32 -- possible?
I use klm8g1getf. It’s 8GB and about $5 from LCSC, easyEDA has the footprint and symbol. I run mine at 52mhz, 4-line mode. I’m able to playback 20 stereo wavs at once @44.1k 16bit. Writing is a lot slower but 8 should be possible. I wrote my own flat file system to prioritize speed, all the standard file systems will slow you down a lot, as far as I could find, sequential reads and writes are much faster, and most file systems don’t do that. https://github.com/marchingband/wvr/blob/main/src/emmc.c

is it possible to port this code to Arduino ide?
https://github.com/marchingband/wvr/blob/main/src/boot.cpp This uses eMMC which is very similar to SD.
- Use samd21 to flash ESP32

My lil drum machine project
I have some stock! if you want one just HMU! More info here : https://github.com/marchingband/wvr
